The Obama Message Machine

President Barack Obama speaks at the University of Nevada Las Vegas on June 7.

Mark Halperin, senior political analyst at Time, man behind The Page, and co-author of Game Change: Obama and the Clintons, McCain and Palin, and the Race of a Lifetime, discusses how the Obama re-election campaign is controlling its message, from vetting quotes in articles to the "drip-drip-drip" Bain attacks.
